The AQ6373 optical spectrum analyzer performs the color analysis function as follows:1. Measure the spectrum 2. Compare the measured spectrum with “color matching functions” as defined by the CIE Using these ...

Wavelength accuracy: Wavelength accuracy is a tolerance to the true value of a measured value when the standard wavelength is measured. Wavelength repeatability:Wavelength repeatability is the stability of ...

Level Accuracy:Level Accuracy is a tolerance to the true value of measured value, when a standard level is measured with a standard wavelength. Level Linearity:Level Linearity is the width of error dispersion ...

We are currently aware of this issue occuring on model AQ7270's with firmware Ver. 1.02. Please download and install the latest firmware version from the Yokogawa software drivers & firmware website: ...

On the AQ7270 OTDR, there is an Averaging Method function with two measurement modes: High Speed or High Reflection. High SpeedThe high speed mode is used to measure all sections using a fixed attenuation setting. If ...

The Cursor value displays the level in dB that the signal is above the noise floor of the optical port you are connected to. The noise floor is basically the Dynamic range. This lets you know if you are approaching the ...

To delete all user files from the internal memory of the AQ7270 or AQ7275 OTDR, follow the procedures listed below:
Power up the AQ720 or AQ7275 OTDR
Press the OTDR soft key
Press the FILE key
Press the ACTION soft ...

The resolution is controlled by 3 factors:
Input Slit
Detraction Grating
Output Slit
The resolution setting controls the output slit disk. This disk has a fixed number of slits in it. Since the setting only control ...

The Chopped Light mode is used:
To increase measurement level sensitivity by cutting the high frequency noise
To detect only the light that the LS emitted, effective for free space measurement. In free space ...

You can restore all settings for the AQ637X series OSAs to their factor defaults by performing a parameter initialization. This will clear all current parameter setting values and data as well as alignment adjustment ...

The maximum input power that the AQ6370B can measure for pulsed light measurements is +20dBm per resolution at full span, per channel. Keep in mind that this limit is applicable to an averaged power of pulsed light, ...

If the AQ637X series OSA is already running and you attempt to connect an external display, the OSA will not automatically detect the external display. The OSA will need to be re-booted before it can recognize and ...

If you are performing wavelength calibration using the instrument's built-in light source, the warning message is an indication that the monochromator needs to be repaired.
Please visit our Contact site to locate ...

The cursor value displays the level (dB) of the signal that is above the noise floor of the connected optical port. The noise floor is the dynamic range. This lets you know if you are approaching the maximum distance ...

The SU2005A-LCC universal connector is physically compatible with AQ7275, but we do not recommend it because we expect poor connection repeatability and return loss. We cannot guarantee the performance of AQ7275 when ...

The AQ6370 OSA cannot load and re-display the data saved by an AQ6370B. However, the AQ6370 Viewer software can display the data saved by both instruments. Also please note that the AQ6370B OSA can load and re-display ...

The warning "142 WL calibration failed" is displayed when a level of light source is not enough at wavelength calibration or calibration cannot be executed because wavelength difference is out of calibration ...

The following are the specifications for the AQ2200-111 1490nm DFB Module:- Center wavelength: 1490nm+/-10nm- Wavelength accuracy: 0.05nm- SMSR: 30dB or morePlease refer to the datasheet for the AQ2200-111(1310) ...

The meaning of "Monitor port: -13 dB" is that -13 dB corresponds to about 5% (10Log(0.05) nearly equals to -13). That is, output power is divided by an optical coupler at a ratio of 95:5, and 5% is for monitor ...

The WDM Analysis calculates a central wavelength by a threshold method. A peak wavelength is acquired by a central wavelength between wavelengths, where the level is at -3 dB points on both side of the peak.

No, although the basic shape is the same for both the AQ9335 and AQ9335C, the internal physical deisgn for the AQ9335C has been changed slightly to fit the AQ2200 series sensor modules for optimum accuracy. You will ...
